Gears are an important part of the reducer and play an important role. Hansheng PGH series uses helical gears. Compared with spur gears, the position of the helical gear reducer shaft is freer. Reduce noise. If helical gears are used, the noise will be much lower than straight gears at the same speed, and the transition of helical gears will be smoother. Therefore, the noise caused by the sudden change of contact is much smaller than that of flat teeth. The helical gear has a large overlap, and the number of teeth entering mesh at the same time reduces impact and noise, making the transmission more stable and able to withstand high-speed and heavy loads. The number of teeth to avoid undercutting during processing is small, and the corresponding gear size must be small. Therefore, when the transmission and transmission ratio are the same, the reducer using a helical gear must be small and high in precision.

1. What is a planetary reducer?

 

The planetary reducer is a reducer composed of multiple planetary gears, a sun gear and an inner cam. It is mainly used to reduce the speed of a high-speed rotating output shaft and increase the torque output.

 

2. Why are most gear reducers made with helical teeth?

Compared with spur gears, the position of the helical gear reducer shaft is freer. Reduce noise. If helical gears are used, the noise will be much lower than straight gears at the same speed, and the transition of helical gears will be smoother. Therefore, the noise caused by the sudden change of contact is much smaller than that of flat teeth.

 

3. What are the advantages of planetary reducers?

 

Planetary reducers have the advantages of small size, large transmission ratio range, small radial size, high efficiency, high reliability, and low noise.

 

4. What are the application areas of planetary reducers?

 

Planetary reducers are widely used in mechanical equipment, robots, industrial automation, medical medicine, precision instruments, aerospace and other fields.
